Going down the list--
Yeah, I think my love of Jordan Adams' game is well known here...very Harden-esque, from the frame to what appears to average athleticism at first glance, to the way they utilize the three point line to at-rim scoring with little love for the mid-range game. I think where Adams may fall short of Harden potential is what I think is poor passing ability, but he might be a better ballhandler and defender, and to be honest I prefer those trade offs, as there's more two-way potential. The long range shooting isn't quite there yet but that's the case for most freshmen with a ton of responsibility, and I think he'll round out into a good shooter in time once he gets fully acclimated. A lot of transferable skills to work with. Don't forget, at points during his freshman and sophomore years, Victor Oladipo was once a late 1st round pick. Adams can have that sort of surge.
Russ Smith--eh. He just ticks too many wrong boxes for me. The game-test would make many a fan wonder about BJax, but Bobby had really good upper body strength and could really defend. The league is getting bigger and stronger at the PG position than it was in the early 2000s, and Russ...is only 160 lbs. That's already a huge red flag. I also don't think he's as good a shooter as BJax, and he's a SG through and through which means he'll need to be crossmatched offensively and defensively. Negative assist to turnover ratios in college is a HUGE red flag, especially for a player entering his senior year. I think he built up too much college goodwill not to be drafted, but my tentative ranking is actually in undrafted territory right now. He's on the older side, we know his game...and I'm not seeing really any seamlessly transferrable skills to the NBA. Shot-creating ability is something that can be found in the bargain bin.
If Harrell continues in his normal trajectory of development, I'm thinking he's more of a 2015 prospect, and he wants to really eke it out maybe he'd near all four years in college. Granted, he's only a freshman, but that's where we start forming conclusions about players. I see some rebounding potential here but I'm thinking the offense will be a complete wreck at the next level, because he's not hitting any of the three markers (shooting touch, offensive elusiveness, passing/handles) we're looking for. His frame is just a-ok for the next level, at best. Not much else to say, but I think he's at least a 3-4 year college player. Another note? Louisville has an awful track record for first round picks. Not a big fan of their ability to produce NBA talent. So there's all that we got to keep in mind. Same goes for Russ Smith, who also goes there.
